In this study, a numerical study of laminar natural convection flow of air in a vertical channel with only one sinusoidal obstruction is performed. The wall containing the obstruction is assumed to be heated while the other wall is assumed to be adiabatic (asymmetric heating). The governing elliptic equations are discretized in a two dimensional domain using the finite-volume method with non-staggered variable arrangement and the PISO algorithm for the velocity-pressure coupling is employed. Simulation was carried out for a range of amplitude of the sinusoidal obstruction a = 0.0-0.5, aspect ratio A = 5, channel Rayleigh number Ra* = 102 to 2.105 for a fluid having Prandtl number equal to 0.71. Streamlines and isothermal lines represent the corresponding flow and thermal fields. Local and global Nusselt number distributions express the rate of heat transfer. |
